# What is the formula of concrete quantity?

## What is the formula of concrete quantity?

Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

## How many bags of cement make 1m3 of concrete?

Approximately 29 bags are required for 1m3 of cement.

How do you calculate the aggregate amount of concrete?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

### How much concrete is needed for a 10×10 slab?

### How many 20kg bags of cement makes a cubic Metre of concrete?

108 x 20kg bags
one 20kg bag will cover an area of 1.1m2 to a depth of approximately 10mm. or 108 x 20kg bags equates to one cubic metre of mixed concrete.

How do you calculate material quantity in construction?

Approximate cost on various work of material to complete the construction for 1000 ft 2

1. Total Cost. = Builtup area × Approx cost per sq. ft. = 1000 × 1000. = 1000000.00 Rs.
2. Amount of Aggregate Required. = Builtup area × 0.608. = 1000 × 0.608. = 608.00 Ton.
3. Flooring. = Builtup area × 1.3. = 1000 × 1.3. = 1300.00 Sq.

#### What is the formula for calculating concrete?

How to Calculate Concrete Formula Know that the formula for calculating concrete consists of the following: ( (length x width x height)/27) x 1.05 = Total concrete needed plus 5 percent extra. Measure the length, width and height of the area to be filled. Multiply the length by the width by the height in the following manner to determine how many cubic feet of concrete you need: 100 x 100 x 1/3

How do you calculate concrete?

How to calculate concrete: Determine how thick you want the concrete. Measure the length and width that you’d like to cover. Multiply the length by the width to determine square footage. Convert the thickness from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet.
